APPARATUS FOR MOLDING MASSE-QUITE.

SPECIFICATION forming part of Letters Patent No. 616,679, dated December27, 1898.

Application filed December 29, 1897. Serial No. 664,408. (No model.)

.To @ZZ whom t may concern:

Be it known that I, LEOPOLD MAY, a subject of the Emperor ofAustria-Hungary, residing in the city of Vienna, in the Empire ofAustria-Hungary, have invented a new and useful Improvement in Apparatusfor Molding Masse-Ouite and Analogous Substances into Bars or Strips, ofwhich the following is a specification, and for which there have beengranted an Austrian patent, No. 47/4,1l7, dated October 28, 1897, and aBelgian patent, No. 130,687, dated September l5, 1897.

This invention consists in the combinations hereinafter described and.claimed of moldbodies and cores and appurtenances thereof by whichpartly-Huid substances, such as the masse-cuite of sugar-renners, aremolded into bars of a desired cross-sectional form and treated withclairce or any liquid clarifying agent.

Figure l of the accompanying drawings shows, partly in longitudinalsection and lpartly in elevation, abar-molding apparatus embodying myinvention. Fig. 2 shows in part a plan and in part a horizontal section;Fig. 3, a transverse vertical section. Figs. 4, 4a, 4b, 4C, and 4dillustrate in horizontal section, on a larger scale, various forms ofthe mold body and core.

Two important elements of the apparatus consists, as may be understoodby reference to Fig. 4, of a hollow mold-body ct and a hollow core a ofsuitable form. In the example represented in that ligure the mold-bodyconsists of an upright tube of square horizontal section open at top andbottom, and the core is a tube of cross-shaped horizontal section closedat the top and bottom, the edges of the arms of the cross fitting withinthe walls ofthe 1nold-box, so as to form therein four cavities 0.2,'which are open at top and bottom and which constitute as many molds,into 'which the mass to be molded-massecuite, for example-is charged forthe purpose of producing bars, strips, or slabs.

The mold-body a and core a' are preferably made conical or taperingupward in the direction of their length for the purpose of facilitatingthe removal of the core with the molded bars, strips, or slabs from thetubular moldbody in a direction lengthwise of the latter. Such amold-body and core may of coursebe made of any other suitablecross-section. Thus, for eXample,'in Fig. 4 the mold-body a is made ofan oblong rectangular cross-section, into which there is inserted a coreconsisting of a tube a of cross-shaped cross-section, which is closed attop and bottom and has two short and two long arms corresponding withthe inside of the tube, so as to form in the tube or body a fourcavities a2 or molds of oblong rectangular cross-section for theproduction of slabs from the masse-cuite.

In Fig. 4b the tube a, constituting the moldbody, is of squarecross-section, and into itis inserted the inner tube a', closed at topand bottom, which constitutes the core and which is also of squarecross-section, the four side walls of said tube Ct severally projectingoutward beyond the adjacent side, so as to form wings a* and form in thetube or mold-body a the four hollow mold-cavities a2 (which are also offlat rectangular cross-section, for the reception of the masse to bemolded.

In Fig. 4c the tube or mold-body is represented as circular incross-section, and the inner tube or core a' is of correspondingcrosssection, but has provided on it oppositelysituated projections orribs aomunning lengthwise of it. By this means there are formed in thetube or body a two mold-cavities a2 of semi-annular shape incross-section for the reception of the masse-cuite, so that therefore inthis arrangement two bars of semiannular cross-section are produced.

Obviously the tube ct and core a may instead of being cylindrical havean elliptical or similar cross-section. f

The core ce of cylindrical cross-section may,

as shown in Eig. 4, alsobe made without the projections ctothat is tosay, it may have a smooth outer surface and be inserted in the outertube or mold-body ct, so that in the latter there is formed only ahollow space a2 of annular cross-section for the reception of themasse-cuite. I/Vith this arrangement there is therefore formed only onebar of annular cross-section.

The two last forms can be made easily and roo cheaply, and also theformation of the bars of sugar or the like iu these molds has been foundto be extremely advantageous.

As shown in Figs. l to 3, any desired number of the above-specifiedmold-bodies a, of which the form shown in Fig. is selected by way ofexample, are associated together and fixed at their upper and lowerends, respectively, into frames b and b', provided with handles b2, andthe hollow bodies thus united in a group or a bundle are placed upon atight drainage-box c and attached thereto by means of clamping-screwsc', provided on the latter.

The mold-bodies c may of course be fastened singly in frames b b',provided with handles, and be attached upon the box c. This isparticularly advisable in cases where the mold-bodies u are of largesize, as shown, for example, in Fig. 4a.

The box c is provided at its upper surface with apertures, which aresurrounded by packing-surfaces and correspond with the lower mouths ofthe bundle of mold-bodies placed upon it, which apertures are adapted tobe closed by means of plates c3, which can be moved up and down fromoutside the box c by means of suitable adjusting devices c2- nuts andscrews, for example. YVhen raised, the plates c3 constitute the bottomsof the mold-cavities a2, which are formed in the mold-bodies a by theinserted cores c,as shown at the right hand of Fig. 3.

From the bottom of the box c there projects an outlet c4, which iscommon to all the apertures in the top thereof and which is connectedwith an air-pump c5. -Upon the upper frame b of each bundle of moldsthere is placed a cup-shaped receiver which is open at top and bottoniand is provided with handles on its sides and with a packing edge on itsunder surface and into which receiver is introduced the iluidmasse,which Vruns therefrom into and lls the hollow mold-spaces a2,formed in the mold-bodies a.

Into the receiver d there is inserted a perfoi-ated plate e, which isprovided with handles c* and which forms at the same time a removablebottom for said receiver, and to the perforations of which there areconnected upwardly-projecting tubes c', which are situated exactly overthe mold-cavities a2 of the bodies a and which have a cross-sectioncorresponding exactly to that of said cavities.

By inserting the plate or bottom e into the masse, which is still fluidand in excess in the receiver CZ, the masse is forced into the tubes e',and thus in addition to making up fory the contraction of the massecaused by settling in the mold-spaces also forms feeding-heads for themolded bars, which feedingheads can be separated quite smoothly bylifting off the plate or bottom c from the soliditied bars.

After the removal of the plates e the clairce is poured into thereceiver CZ, which sits tight upon each bundle of molds and which alsoconstitutes a measuring devicefor the necessary amount of clairce, andthen the plates c3 are moved down by means of the adjusting devices c2until they bear against rubber disks c6, (see Fig. 1,) which serve tomake tight joints for the apertures of the plateadjusting spindles. Thenthe air-pump cS-is set in operation, whereby the drainage-box c isdeprived of air, and the molasses is drawn by suction from the sugarbars and its place is taken up by the clairce.

Vhen the whole of the clairce has entered the sugar bars, the suctionprocess is interrupted, and after loosening the clampingscrews c' allthe bundles of'molds are moved from the drainage-box c and are placedinto a centrifugal apparatus, (not shown,) which expels the superfluousclairce from the sugar.V After the bundles of molds have been removedfrom the centrifugal apparatus the molded bars or slabs are loosened oneafter the other by means of any suitable loosening apparatus and thenremoved from the molds to be further dried, if necessary, by anysuitable means.
